Answer:
Nil
Step-by-step explanation:
Given that,
There is a cash shortage.
All borrowing, repayments, and interest payments occur on the last day of the month.
Interest rate = 1% per month
Debt = No debt before 1st January
The amount is borrowed at the end of the month of January and interest is paid in the following month i.e February.
Hence, the amount of interest expense incurred for January is nothing, it means zero.
